Get type of an sq object

Description

Returns type of sequences/alphabet contained in sq object.

Usage

sq_type(x, ...)

## S3 method for class 'sq'
sq_type(x, ...)

sq_type(x) <- value

## S3 replacement method for class 'sq'
sq_type(x) <- value

Arguments

x	[sq] An object this function is applied to.
...	further arguments to be passed from or to other methods.
value	[character(1)] The name of destination type - any valid sq type.

Details

Types returned by this function can be passed as argument to functions like random_sq and find_invalid_letters.

Functions that manipulate type of sequences: find_invalid_letters(), is.sq(), substitute_letters(), typify()

Examples

# Creating objects to work on:
sq_ami <- sq(c("MIAANYTWIL","TIAALGNIIYRAIE", "NYERTGHLI", "MAYXXXIALN"),
             alphabet = "ami_ext")
sq_dna <- sq(c("ATGCAGGA", "GACCGAACGA", "TGACGAGCTTA", "ACTTTAGC"),
             alphabet = "dna_bsc")

# Extracting type of sq objects:
sq_type(sq_ami)
sq_type(sq_dna)

# Classes are tightly related to these types:
class(sq_ami)[1]
class(sq_dna)[1]
